What about Lightroom users that aren't cloud fanatics?

Why can't you get a standalone version of LR 6? Why must I create a bogus adobe sign-in just to install a standalone version? I neither need, nor want, the cloud capabilities on all my machines. I've got a CC subscription for those machines I do want it on, but I'm willing to pay, and have paid, for a standalone license but it still requires me to sign into an account. That is completely broken. How is Adobe going to take care those of us who've not become completely besotted with the Cloud Kool-Aid?

That is true, but when you try to install it, you're required to sign in with an Adobe ID.

If that ID is associated with a CC subscription and you've got the max number of installations for those products, the Application Manager will not let you proceed unless you deactivate them.

You need to create another adobe ID to proceed, or if you've got one that's not associated with CC, use that one. I'm frustrated by the fact that I've to sign in, register, and then sign out of an Adobe account.

Oh, and when you sign out, you get a dialog box that informs you that your software will be deactivated by doing so. It turns out that's not the case, but it is disconcerting nonetheless.

You shouldn't have to sign in to a site if you've got a valid serial # (#'s in the case of upgrades) which I have.

I am using the creative cloud installation, so I haven't gone through the process of installing the standalone Lightroom 6. But I believe that if you follow the instructions at the top of this link, you will be able to get your Lightroom 6 licensed with a serial number:
